Application May 29, 1946, Serial No. 672,928 In Sweden February 2, 1945Section 1, Public Law 690, August 8, 1946 Patent expires February 2,1965 4 Claims.

The invention relates to improvements in push-sledges, the runners ofwhich are made of flat-strips of iron and placed on edge. These runnerswill easily slide on ice and hard snow, but will also readily grateunderneath the snow when the snow is less hard, and they will therebyimpede the desired easy sliding of the pushsledge. This inconveniencecan be overcome by turning the fore part of the runners 90, in order tomake this part of the runners rest flat on the ground. Also the backpart of the runners may be turned 90, only leaving the middle part ofthe runners standing on edge.

One form of the invention is illustrated in the accompanying drawingshowing a push-Sledge, the runners of which are turned 90 on both thefore part I and the back part 2 in respect to the middle part 3. Thusthe middle part 3 stands on edge as usual, while the other parts I and 2rest at on the ground.

By making one or more parts of the runners to rest flat on the ground,the runners will not so readily grate underneath the snow, but will onthe contrary pack the snow and slide over it. At the same time, therunners maintain their elasticity in the middle, so that the push-Sledgemay be steered and braked even as well as those with the runnersunturned.

By the improvement described, this pushsledge may stand a heavier loadthan ordinary ones.

I claim:

1. In a push sledge a runner of flat strip material, said at strip beingplaced on an edge thereof, a portion of said strip being twisted atright angles to the remainder of said strip and a substantial area ofsaid twisted portion being in the plane of the lower edge of said strip.

2. A runner for push sledges comprising a strip of resilient materialhaving two relatively narrow sides and two relatively wide sides, saidstrip being twisted to bring a portion of one of said narrow sides and acomplementary portion of one of said wide sides into alignment in thesame plane to make surface contact.

3. A push sledge having a plurality of runners of resilient stripmaterial, said runners each having two relatively narrow sides any tworelatively wide sides, each said strip being twisted to bring a portionof one of said narrow sides and a complementary portion of one of saidwide sides into alignment in the same plane to make surface contact.

4. A runner for push sledges comprising a strip of resilient materialhaving two relatively narrow sides and two relatively wide sides, saidstrip being twisted at each end thereof to bring a central portion ofone of said narrow sides and the complementary end portions of one ofsaid wide sides into alignment in the same plane to make surfacecontact.
